Title: Cathodic protection of steel within a covering material
Inventor: WHITMORE DAVID
IPC: C23F13/16
Filed: 2003-12-08
Abstract: Cathodic protection of an existing concrete structure, including a steel member at least partly buried, such as steel rebar, in the concrete structure, is provided by embedding anodes into a fresh concrete layer applied over an excavated patch and/or as a covering overlay. The anodes are embedded at spaced positions or as an array in the layer and connected to the rebar. A  corrosion inhibitor is added into the fresh concrete at least at the interface and more preferably in admixture with the fresh concrete which acts to reduce the flow of ionic current to the steel or between the anode member and the steel in the fresh covering material without significantly increasing the resistivity of the fresh covering material and without inhibiting the ionic current between the anode member and the fresh covering material. In this way the current to the steel in the existing concrete is maximized to maximize the cathodic protection to the existing steel which is the primary target.
Patent CA-2510137-A1 (CA)
Title: Oilfield pipe-handling apparatus
Inventor: WELLS KERRY
IPC: E21B19/15
Filed: 2005-06-17
Abstract: A trailer-mounted pipe-handling apparatus has an elongate cradle swivelable about a longitudinal swivel axis for loading or offloading pipe at a well site. With the cradle horizontal, and swiveled into a loading position, loading arms receive a pipe from a loading rack, whereupon kicker members move the pipe from the loading arms into the cradle.  With the cradle swiveled into a neutral position supporting the pipe, a swing arm raises one end of the cradle while simultaneously drawing its other end horizontally along a base track, thus placing the cradle in a tilted configuration. The raised end of the pipe can thus be positioned above the floor of a drilling rig or service rig for connection to the rig hoist, which can then lift the pipe out of the cradle. Pipe may be removed from the well using a similar, reverse procedure. The rig hoist positions a removed pipe in the tiltingly elevated cradle, which is then lowered to the horizontal position. The cradle is then swiveled to an offloading position, allowing the pipe to roll out of the cradle onto an offload rack.

Title: Inhibition of hiv-1 replication by disruption of the processing of the viral capsid-spacer peptide 1 protein
Inventor: SALZWEDEL KARL
IPC: C12Q1/68
Filed: 2004-01-29
Abstract: Inhibition of HIV-1 replication by disrupting the processing of the viral Gag capsid (CA) protein (p24) from the CA-spacer peptide 1 (SP1) protein precursor (p25) is disclosed. Amino acid sequences containing a mutation in the Gag p25 protein, with the mutation resulting in a decrease in the inhibition of processing of p25 to p24 by dimethylsuccinyl betulinic acid or dimethylsuccinyl betulin, polynucleotides encoding such mutated sequences and antibodies that selectively bind such mutated sequences are also included.  Methods of inhibiting, inhibitory compounds and methods of discovering inhibitory compounds that target proteolytic processing of the HIV Gag protein are included.

Title: System and method for stabilization of internal structures
Inventor: SPITLER JAMES
IPC: A61B17/70
Filed: 2004-10-21
Abstract: There is shown a system and method for reducing the difficulty in percutaneous placement of a spine stabilization brace by coupling the brace to a pedicle screw in a single assembly. The brace-screw assembly is delivered along with an anchor extension through a cannula for anchoring in the vertebrae pedicle.  The anchor extension becomes a cannula for working on the brace from the exterior of the patient, as constructed with a slot opening along two sides.  Once the screw portion of the brace~screw assembly is locked in place with respect to the first vertebra, the proximal end of the brace is below the skin line. The brace is then repositioned so that the proximal end leaves the cannula through one slot and is captured by a corresponding slot positioned in a second cannula coupled to a second anchor. Once captured, the proximal end of the brace is guided by the second cannula to a receptacle positioned in the second vertebra.
